"You see, Ash, I've been experimenting with a new energy wave that, when transferred through electricity, should convert any Pokemon zapped by it into the same kind as the one who used the move." explained the Professor as he transferred Pikachu into the computer, "When the Pokemon is put into a computer, it becomes data, and it can be altered like any other line of code. This is how you get creatures like Porygon, Mewtwo, and even Ditto... Except, unlike Team Rocket, I plan on using this technology to bring back species that have become endangered. Think about it, Ash, Snorelax, Dragonite, and all the other exceedingly rare Pokemon will be brought back from the brink of extinction!"
"But Professor..." said Ash, "Won't the Pokemon not like being transformed?"
"Nonsense, my research shows that all Pokemon are near identical DNA wise, and each one has the potential to be something else entirely. Just look at Alolan forms." answered the Professor.
Ash pondered that a second, "But... Suppose the Pokemon isn't good for breeding?"
Oak grinned smugly, "My boy, I have thought of that and so much more. The sequence has trace amounts of temporal energy I managed to reconstruct after studying Dialga. I used it to either speed up or reset biological clocks, making whatever creature who gets shocked the perfect breeding age as well as curing any infertility problems. More so, it's contagious. Any Pokemon hit instantly knows the move. Also, mothers who obviously wouldn't attack their children will be producing special milk that utilizes similar temporal energies to put the child back into the womb, where, like a butterfly in a cocoon, they quickly mature into an adult of their new species. And, finally, as a safety measure, I programmed in a kill code. I type a command in my console, and the move becomes innert. We'll retain the population gained, but won't have to worry about over population."
Pikachu exited the machine, seemingly no worse for the wear.
"Alright, professor, if you're sure." said Ash, "So... Why did you have me bring over Mr. Mime?"
"Well, Pikachu will have to stay somewhere until my Lab Rattatas get in from Saffron, and we wouldn't want him turning all yours and Gary's Pokemon into pikachus by accident, would we?" said Oak bluntly, "So, he'll have to stay at your house tonight. Leave him there, ok. It will only be until tomorrow."
"Alright, Professor, if you say so." said Ash, "May's coming to visit today, anyway, so we were just going to see a movie. How about it, Pikachu, you want to spend some quality time with my mom?"
Pikachu frowned. He'd been looking forward to today. Now, because of Oak's experiment, he would get to go.
"Pika-pi..." said Pikachu, morose.
"Don't worry, Pikachu." said Ash, "Its only till tomorrow, I swear!"
*Later, at the Ketchum Residence*
"Bye Mom, take care of Pikachu for me!" called Ash, as he rushed off to meet his friend.
"Ok, sweetie. Have fun." Mrs. Ketchum smiled, in her motherly way.
Pikachu was still down in the dumps about not getting to go.
Delia couldn't help but notice the Pokemon's sour mood.
"Oh, come on, Pikachu, Ash will be back before you know it!" she chirpped in a way too chipper tone, pinching Pikachu's cheeks, "Come on! Let's turn that frown upside down!"
Pikachu growled. Ash's mother always did annoy him. His emotions got the better of him, and a spark flew from his cheek onto her fingers.
"YOUCH!" she shouted, drawing her hand back, "You're not in the mood, I get it! No need to attack me. Fine, you sit there and pout, I'm going to go take a bath and get dinner made, kay?"
Pikachu sighed and rolled over, dozing off.
Delia harrumphed, and trotted off to the bathroom.
She started running bath water as she stripped and looked at herself in the mirror. The years had been kind to her. Despite having a child... Let alone one as troublesome as Ash could be, and doing it all as a single mother? It's amazing she didn't look like trubbish.
But, the years had started to catch up, bit by bit. Her breasts had begun to sag and shrink and she could see wrinkles forming. She stretched out her crows feet, briefly fantasizing about a face lift, but when she took her hands away the skin remained taught.
She stroked her face. Baby smooth. She had never been particularly wrinkly, but now she looked perfect for her age... Even perfect for a much younger woman.
A pain in her nipples took her attention away from her new face. They felt sore, like when she used to breast feed. Delia massaged them, finding they were extremely sensitive and giving off discharge.
"Oh... Oh my..." she moaned. She hadn't properly played with herself in years. It felt good just to be touched, even by her own hands.
She circled her areolas, occasionally stopping to twist the rock hard centers.
After a few minutes, she finally managed to stop her hands, and found herself in a cold sweat.
"Calm yourself, Delia." she said aloud, bracing against the sink. She wanted desperately to go all out, but she still had dinner to cook, clothes to wash, and all these other chores. It wasn't the time or place to start playing with herself.
She finally got in the tub and started soaking. After a few minutes, she broke the shaving cream. Her unnoticed areas had gotten rather hairy since the last time she waxed.
She slathered her whole body in the cream and started shaving her arms. Soon it got to her arm pits, which horrendously ticklish, but she perservered. Then came the legs, which... Didn't seem the right color. Delia could swear she saw flecks of blond amongst her chestnut Brown.
Finally, she started shaving around her most private area. It had become a virtual jungle down there. It was too much for even her razor.
"So, you wanna do things the hard way?" asked Delia, pretending to be serious, then giggling. Why was she acting so playful all of the sudden?
She pulled the hair trimmer She used on Ash's hair out of a drawer and sat on the toilet. What Ash didn't know wouldn't hurt him, right?
She flicked on and the comb-like electric blade began buzzing in her hand.
She took aim and started taming the beast on her crotch.
Things went smoothly at first, but as the vibrating razor got closer to her slit, it started feeling a little too good. Liquid started to gently ooze out of her vagina, puddling on the toilet lid.
Delia could smell herself. Fishy, hot, heavy. She was starting to burn up.
She couldn't take it anymore. She flicked off the the trimmer, and gingerly stuck one finger into her void.
Her insides felt warm and wet with mucus.
"Oh... Oh Arceus..." she swore, as she slowly went in and out of herself.
One finger became two, and her motions slowly increased in speed. Soon, it became an erratic pumelling of sorts, as she continuously kept fingering herself, knuckles slapping wetly against her crotch. Her other hand wouldn't be left out and reached for a breast, cupping it and twisting the nipple hard.
She could feel a slight pain as her euphoria heightened, like a tugging of her ears, but she ignored it as her hand was now a blur, fisting her engorged pussy with all her might.
Something finally pierced her euphoria, a distant buzzing noise... THE ROAST! Delia ran out of the bathroom without even a towel. If she had paused for even just a moment, she might have seen her now elven ears and eerily rosy cheeks in the mirror.
Delia got to the kitchen, still soapy and wet. She went to unplug the crockpot, but as she did, her wet hands touched something grounded, sending a shock into her system.
Delia had never experienced a shock like this before, it only seemed to further ignite her insane lust. It traced all over her body, confused about where to call home. It tried staying in her nipples, nearly causing her to scream from the pleasure, then it entered her tight, oozing vagina. That was it. She reached the limit. She fell to her knees spasming, body clenching tighter and tighter as she came. Her lubricrating fluids were all over her legs and the floor. The electricity finally settled on her cheeks, being absorbed into her new electricity sacs.
Delia braced her arm on the counter and for to her feet. She finally saw her reflection on the window. Her increasingly cunicular ears, her red circles, and now an ever darkening nose.
"Wh-what's happening to Pika? What?" Deliah was confused, her mind was becoming clouded.
She felt her face, the nose was soft and fuzzy. It twitched at her touch. She clapped her hand to her mouth in horror, and felt fur growing. It started at her face but spread like an itchy, irritating rash, yellow and brown fur growing all over her body.
When the irritation died down, her face started to hurt, like someone was punching her mouth from the inside. She wept in pain and sorrow as her mouth slowly reformed into a muzzle.
"Pika" she cried, asking the world why "Pikachu..." she cried even more, she couldn't even talk anymore.
The same inner pain started to form at her rear. She gripped her sides as her spine stretched and twisted out of her coccyx. She thought it was almost done when SNAP, her growing apendage went at a ninety degree angle. She was almost relieved it went back to simply growing when SNAP, her tail did it again. Four more times, her growing tailbone cracked and reformed as it grew, until she was left with a giant yellow and brown, heart tipped lightning bolt growing out of her ass.
Her raging body finally started to quiet. Her cheeks sparkled as she lay there exhausted, panting "chu" over an over. What more could be done to her?
"MOM, WE'RE HOME EARLY! Movie was canceled after Team Rocket showed up and- MOM?!?!"
